Abstract Homogeneous mixed-valence (MV) behaviour is one of the most intriguing phenomena of f-electron systems. Despite extensive efforts, a fundamental aspect which remains unsettled is the experimental determination of the limiting cases for which

A Kondo lattice of strongly interacting f-electrons immersed in a sea of conduction electrons remains one of the unsolved problems in condensed matter physics. The problem concerns localized f-electrons at high temperatures which evolve into hybridiz

The positron annihilation lifetimes were measured using a 48V positron source in noncentrosymmetric cubic single crystals of CoSi, FeSi and MnSi. The following lifetimes were determined from the positron annihilation time spectra: 168(1) ps for CoSi,

The interplay between nontrivial topological states of matter and strong electronic correlations is one of the most compelling open questions in condensed matter physics. Due to experimental challenges, there is an increasing desire to find more micr

We show that the resistivity plateau of SmB_{6} at low temperature, typically taken as a hallmark of its conducting surface state, can systematically be influenced by different surface treatments. We investigate the effect of inflicting an increasing

Many discrepancies exist to question the nature of the candidate topological Kondo insulator, SmB6. Here, Jiao et al. observe in-gap states on well characterized (001) surfaces of SmB6, indicating a suppression of the Kondo effect at surface, which r

The predicted interplay between Kondo physics and nontrivial topology in SmB_{6} has stimulated many experimental reports, some of which are in apparent contradiction. The origin of the dispute may lie in the fragility of the Kondo insulating phase i

We report X-band Electron Spin Resonance (ESR) experiments on ≈ 0.2% and ≈ 0.7 % Er3+ doped SmB6 at low temperature (4 K - 40 K). The crystal field ground state of Er3+ in SmB6 is a Γ8 quartet with a nearby Γ6 excited doublet. The angular depen
